Lab results library
Every batch is sent to an independent laboratory before we sell it. They check four things: how pure it is, that it is the right compound, that it carries no bacterial endotoxins, and that it is clear of heavy metals. Every certificate is published here, so you can read it before you order rather than after.
| Compound | Purity | COA | |
|---|---|---|---|
| Retatrutide | ≥99% | ||
| Tesamorelin | ≥99% | ||
| CJC-1295 No DAC + Ipamorelin | ≥99% | ||
| BPC-157 + TB-500 Blend | ≥99% | ||
| KLOW Blend | ≥99% | ||
| MOTS-c | ≥99% | ||
| NAD+ | ≥99% | ||
| SS-31 | ≥99% | ||
| Selank | ≥99% | ||
| Semax | ≥99% | ||
| GHK-Cu | ≥99% | ||
| Kisspeptin-10 | ≥99% | ||
| Melanotan II | ≥99% | ||
| PT-141 | ≥99% |
What we test, and why
Purity is only a quarter of the picture. A peptide can come back 99% pure and still carry bacterial endotoxins or traces of heavy metals left over from how it was made, and a purity number alone will never show you either one. So we test for all four, on every batch, before it goes on sale.
How pure it is
The sample is separated into everything it contains, and the compound you ordered is measured as a percentage of the total. That is where the ≥99% figure comes from. We publish the full chart, not just the number.
Method: HPLC
That it is the right compound
The molecule is weighed and matched against what the peptide should weigh. This is the check that catches substitution, because a very pure sample of the wrong compound is still the wrong compound.
Method: mass spectrometry
No bacterial endotoxins
Endotoxins are fever-causing fragments left behind by bacteria during manufacture. A sample can be 99% pure and still carry them, because a purity test simply does not look for them. This one does.
Method: LAL test
No heavy metals
Making a peptide involves reagents, catalysts and steel equipment, any of which can leave metal traces behind. This screens for them down to parts per million.
Method: ICP-MS
Lot matching
The lot number on every certificate matches the lot printed on your vial. That link is the entire point of a COA, and the first thing worth checking on anyone's.
